Already known for having one of the best smartphone cameras on the market, iPhone may be upgrading to not one but two rear-facing cameras to capture those shots. Though still eight months away from a possible iPhone 7 launch, the rumor mill is spinning indications the iPhone 7 Plus will come with a dual-camera system on the back of the device. This according to Mac Rumors. The functionality of a dual camera is unclear, though such a system would make 3D capture possible.
